➤ Installation

npm i @appnest/masonry-layout

➤ Example

Import @appnest/masonry-layout somewhere in your code and you're ready to go! Simply add the masonry layout to your html and you'll be singing and dancing from not having to build the masonry layout yourself.

<masonry-layout>
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
</masonry-layout>

➤ Customize

Customize the functionality by applying the attributes.

Amount of columns

The cols attribute specifies the amount of columns. The default value is auto which ensures to distribute the elements based on the available width.

<masonry-layout cols="5">
  ...
</masonry-layout>

Spacing between items

The spacing attribute specifies how many pixels the spacing between the elements should be. The default value is 24px.

<masonry-layout spacing="50">
  ...
</masonry-layout>

Max column width

The maxcolwidth specifies how many pixels a column can maximum have when the cols are set to auto. The default value is 400px.

<masonry-layout maxcolwidth="200">
  ...
</masonry-layout>

Lock columns

The collock attribute locks the columns. When the columns are locked, the layout will only distribute on the y axis when elements change their sizes. The default value is false.

<masonry-layout collock>
  ...
</masonry-layout>

Change debounce time

The debounce attribute specifies the amount of time in ms the layout reflow debounces each time the size of the masonry layout changes. This reflow is debounced to avoid the layout algorithm being invoked too many times in a row. The default value is 300ms.

<masonry-layout debounce="500">
  ...
</masonry-layout>

➤ Trigger layout

If you want to force layout to can simply call the layout() function on the masonry layout.

document.querySelector("masonry-layout").layout();

If you wish to debounce the layout you can call the scheduleLayout() function instead.

document.querySelector("masonry-layout").scheduleLayout();

➤ ResizeObserver

You might want to polyfill the ResizeObserver. The observer in the component makes sure to distribute the items whenever the size of the grid changes. If this is not polyfilled you will have to call the layout() function yourself when the height of the grid changes. If no ResizeObserver can be found on the window object it will instead re-distribute items when the size of the window changes.
